My HormonologyWhich week are you on in your monthly cycle? Find out what it reveals about what your day has in store:

Week 1
Day 1 (first day of period) to Day 7
Estrogen rises
Today’s Hormone Horoscope: Your urge to window shop, buy and acquire stuff climbs higher and higher throughout your Week 1 and Week 2. Credit for your consumerism goes to rising estrogen. As the level of this hormone goes up, it prompts a bigger surge of happiness-triggering chemicals in the brain when you seek out and obtain fun or useful products!

Week 2
Day 8 to Day 14 or ovulation (here’s how to tell when you’re ovulating)
Estrogen and testosterone rise till they peak
Today’s Hormone Horoscope: If there was ever a week to order the new food, listen to the new band or do the new activity, it’s your Week 2. That’s because high estrogen and testosterone are making you crave adventure and more likely to keep an open mind about what you’re experiencing. So, make a point to break out of at least one boring ol’ rut today and introduce yourself to something totally different!

Week 3
Day 15 (or the day after ovulation) to Day 22
Progesterone rises; estrogen and testosterone drop for half the week, then estrogen rises again
Today’s Hormone Horoscope: You may find yourself looking off into space thinking about nothing in particular or zoning out while doing a task, such as cooking or (eep!) driving. That’s rising progesterone’s fault. As the level of this sedating hormone climbs, it fogs up your brain a bit and makes you prone to drifting off every now and then.

Week 4
Day 23 to the end of cycle
Estrogen and progesterone plunge
Today’s Hormone Horoscope: Try to avoid being a perfectionist today. For instance, when cleaning a room, try not to create an entirely new organizing system. Or when writing a new song, try not to get it perfect on the first pass. Plunging estrogen is making you more easily frustrated with yourself. So, by lowering your self-expectations, you can avoid the irritation that comes from not meeting hard-to-reach goals.
